Felix Instruments F-960 Instruction Manual page 16

For the O2 sensor, an alternative calibration, O2 calibration in
air, can be used instead of setting zero with 100% N2 gas. Please
see the 'O2 Calibration in Air' section for more details on this
process.
The following instructions can be followed to set zero for the
CO2 sensor:
The F-960 is shipped with an external conditioning tube and a
jar of Soda Lime. Fill the conditioning tube with the Soda Lime
granules, keeping the ends packed with the cotton ball filters.
Connect the external conditioning tube to the inlet and outlet of
the F-960, seen below. Continue through the standard set zero
process. The F-960 will prompt the user to use "0ppm/N2". The
Soda Lime external conditioning tube creates a 0 ppm CO2
environment, alternatively, the user can connect N2 gas, which
provides a 0 ppm CO2 environment as well.
*The Soda Lime external conditioning tube is used for the CO2
Set Zero process only.
